The old flash bulbs last longer but look odd after about 1975! The colour temp is daylight, but that does not matter. There is a chance that the camera won't see the flash. I have done this a couple of times and it always worked, can't say why! Stephen Link to comment Share on other sites More sharing options...
Christian Tanner Posted May 28, 2006 Author Share Posted May 28, 2006 thanx stephen! would it help to alter the shutter angle - to increase the chance ot see the flash at all? Link to comment Share on other sites More sharing options...

Hi, As wide as possible, with a 180 degreed shutter there is 50% chance of seeing the flash. Make the flash as bright as possible, that will increase the duration slightly.

Premium Member Hal Smith Posted May 28, 2006 Premium Member Share Posted May 28, 2006 If I had to "fake" a flash and it was real important that it work everytime, I'd rig a magnet onto the camera inching knob and have it sweep past a hall-effect switch driving a solid-state relay. I'd figure out the proper position by having the circuit drive a bright LED in frame and phasing it so I didn't see it in my 2C's viewfinder. If I wanted to fuss some more in advance, I'd open the gate and rig a mirror so that I could watch light coming through the lens and shutter while the camera was running to get the phasing exactly correct. Once I got this far, triggering a strobe or bulb flash attachment would be easy. I'd have a momentary push button switch in series with the solid state switch that I'd push when I wanted the flash. The next time the inching knob came around to the sync position, the flash would fire. Link to comment Share on other sites More sharing options...
